Are you STILL going on about that?

There is clearly a difference between 'negatives' in sentences such as 'I cannot not go', and 'I ain't going nowhere'.

However, my understanding was that they are both 'double negatives' due to sentence construction.

There are many citations to be found on the Internet that also agree with my understanding.

You and the good Doc have clearly pointed out that I was wrong and I accept that.

Happy now?
